BIVALENT

Bivalent

A bivalent engine is an engine that can use two different types of fuel. Examples are petroleum/CNG and petroleum/LPG engines, which are widely available in the European passenger vehicle aftermarket. Bivalent engines can also use hydrogen fuel, as demonstrated by the BMW H7 Series, which has a bivalent V12 engine, and the BMW Hydrogen 7, which is more fuel efficient than the standard H7 Series engine.
